Abstract: Systems and methods are disclosed for receiving inputs at a portable computer used by personal typically operating a delivery vehicle providing delivery services, where the inputs potentially impact completion of a pre-established dispatch plan according to certain delivery criteria. The inputs include modifications to the manifest, updates regarding weather or traffic conditions, or other factors impacting the remaining deliveries. The inputs are examined to determine if modification of the original dispatch plan are warranted, and if so, a signal is generated triggering the processing of the original dispatch plan to produce an updated dispatch plan meeting the certain delivery criteria. The certain delivery criteria may involve commitments for completing deliveries by certain time frames.
